On Waiting Too Long (слэш)

Steve can’t help but think that he and Bucky are the bud of some kind of twisted cosmic joke, teased just within reach of one another only to be catapulted away again. Steve is always too late. Bucky always slipping through his fingers. There isn’t a line that Steve wouldn't cross for James Buchanan Barnes. That much is bombastically obvious in the flaming wreckage of friendships and German airports alike. But he doesn't know what to do now. He doesn't know how to help the most important person in his life.
Or, how things should have gone from the end of Black Panther all the way through Endgame.
